Patent GB-397688-A (GB)
Title: Television method
IPC: H04N3/32
Filed: 1932-10-05
Abstract: 397,688. Television. ARDENNE, M. VON, 19, Jungfernstieg, Lichterfelde-Ost, Berlin. Oct. 5, 1932, No. 27599. Convention date, Oct. 6, 1931. [Classes 40 (iii) and 40 (v).] Relates to the method of television in which the scanning ray is of constant intensity but scans with a variable speed, and consists in preventing frequencies lower than the frequency at which the picture is completely scanned from modulating the potentials deflecting the scanning ray. This results in the time of scanning a complete picture remaining constant. Saw-toothed wave-form oscillations, developed by condensers 26, 27, Fig. 2, charged by current passing through the valves 15, 16 and discharged by a tube 24 and a commutator 41 respectively are applied to the deflecting plates 2, 3, of a cathode ray tube 1, producing an oscillation of the cathode ray on a fluorescent screen 7. The resulting light spot scans a film 11, the current from the photo-electric cell 12 after amplification passing through a filter- 14, which removes the low-frequency components, and being applied to the grids of valves 15, 16 to modulate the saw-tooth waveform oscillations. Since the period of scanning a complete picture is constant, the condenser 27 may be discharged by the commutator 41 driven bv the mechanism for moving the film 11. If the cut-off of the filter 14 is not sharp, the signals are applied to the grid of a rectifying valve 17, Fig. 3, whose output includes a resistance-capacity network 18 which is of high impedance for low frequencies and of low impedance for high frequencies so that the rectified low frequencies bias the modulating valve 16 to compensate for the low frequencies applied to its grid over the condenser 37.

Title: Improvements relating to electric resistance welding machines
IPC: B23K11/31
Filed: 1955-09-29
Abstract: 809,073. Welding by pressure. SLEE, K. V. Dec. 28, 1956 [Sept. 29, 1955], No. 27709/55. Class 83 (4). In an electrical resistance welding-machine having its movable electrode carried by a movable member rockably supported on a fixed part of the machine, the movable member is a rigid member having at one end the movable electrode and rockably supported at its other end by a leaf-spring mounting adapted for withstanding the welding pressure substantially without deflection under that pressure at the instant of welding. In one embodiment a holder 10, Fig. 1, for the adjustable movable electrode 11 is carried at one end of an arm 12 rockably mounted at the other curved end 15 on a fixed part 13 by one or more leaf-springs 14 clamped at one end at 16 to the arm and at the other end at 17 to the part 13. One or more springs 37 to maintain transverse stability are provided. A link 20 from a treadle is connected to a lever 19 pivoted at one end to the frame at 21 and connected at the other end to an adjustable restoring spring 22. The movement of the lever is transmitted to the arm by a spring 26 extending between the lever and a stirrup 28 engageable in one of a series of notches 29 on the arm. The welding pulse is initiated by a switch 30 carried by a member 31 pivoted to the lever and engaging a pin 33 on a part 34 of the arm, when the switch actuator 35 moves away from the part 34. In operation the electrode 11 is caused to descend towards the adjustable fixed electrode 36 by the spring 26 acting on the arm, the curved end of the arm rolling on the spring or springs 14 and the part 34 and member 31 moving down together. When the electrode 11 is arrested the member 31 moves away from the part 34 and a welding current pulse is initiated. In modifications crossed horizontal and vertical springs connect the arm and the fixed part and the electrode holder may be connected to the arm by parallel leaf-springs. In a further embodiment the arm 12, Fig. 3, is mounted on the part 13 in a manner similar to that of Fig. 1 and supports the electrode holder through parallel leaf-springs 45. A lever 19 is pivoted at 21 on the arm and welding pressure is controlled by an adjustable spring 40 acting between a part 41 of the lever and a stop 42 on the arm. The switch 30 is mounted on the lever to co-operate with a screw 46 on the arm. In a modification, Fig. 4, the arm may have a rearwardly-extending foot 48. Pneumatic, hydraulic or mechanical operating means other than treadles may be employed.

Title: Electric batteries
IPC: F01B25/00
Filed: 1930-08-27
Abstract: 366,101. Galvanic batteries. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (National Carbon Co., Inc. ; 30, East 42nd Street, New York, U.S.A.) Aug. 27, 1930, No. 27730/31. Divided on 366,080. [Class 53.] A primary cell in which atmospheric oxygen is the depolarizer comprises electrodes of carbon and a metal and an electrolyte consisting of a solid hydrate of an alkali hydroxide which dissolves when water is added to the cell. The Figure shows a battery of two cells before water has been added to dissolve the electrolyte which is in the form of a solid block 37 cast round carbon and zinc electrodes 11, 12. The upper end of the carbon electrode 11 projects into the atmosphere and the whole electrode is impregnated with a substance which renders it impermeable to the electrolyte. This may be done by adding to the electrode mixture a small quantity of paraffin, petroleum jellymineral oil, or a fatty acid such as stearic acid, The electrode may also be immersed in a solution of petroleum jelly, heavy cylinder oil, and stearic acid in benzine or other solvent. A rubber solution with or without oil may also be used. The electrode may be made by mixing amorphous carbon with a binder such as glucose and baking the moulded mixture under sand or coke dust. Connection to the carbon electrode is made by making a hole in the electrode, spraying the interior with metal, inserting a wire and packing the hole with an amalgam. The zinc electrodes 12 are supported in grooves in opposite sides of the container, and the carbon electrode 11 rests on a rod 15 also supported in grooves in the container. The block 37 of electrolyte is cast round the electrodes in a mould which rests on a shoulder 17 on the container. The electrolyte consists of caustic soda and a quantity of water not greater than 45 per cent of the weight of the caustic soda. The mixture on cooling sets to a solid mass. The cell is closed by a cover 22 which has a filling opening and vent cap 24. The filling opening may be hermetically sealed by means of a diaphragm 25 which is of the same material as the container and is sufficiently thin to be broken when the cell is to be filled. In order to indicate when the correct amount of water has been added a projecting arm may be provided in each cell at the required level of the electrolyte. A cover 35 may be provided for the carbon electrode to prevent accidental contact with water. Openings 36 may be provided in the cover to permit air to circulate round the top of the electrode. Before the battery is sealed a quantity of lime, bentonite, or artificial zeolites &c. is introduced to form an insoluble precipitate with the zinc which goes into solution, thus reducing the zinc concentration in the electrolyte. The container may be of rubber, iron, nickel or other material. Specification 366,080 is referred to.

Title: An improved process for preparing electrode carbon and ash-free coking products from coals
IPC: C01B31/00
Filed: 1935-10-15
Abstract: Ash-free coke suitable for use for making carbon electrodes is obtained by carbonizing coal extracts resulting from the treatment of coal or similar material with solvents, including hydrogenated oils, or phenols, at ordinary or raised pressures, the carbonizing being carried out at temperatures between 500 and 1000 DEG  C. the temperatures being close to but below the disintegrating temperature of the material.  Ash-free pulverized coke may be added to the extract to prevent the formation of porous coke. Suitable extracts of coal, lignite, or peat may be obtained by the process described in Specification 293,808, [Class 32], the temperature of extraction being raised as the temperature of decomposition of the coal rises. The extracts are freed from ash and residual coal by filtration, and the solvent is distilled off, leaving ash-free extracts.  Suitable solvents are tetraline, petroleum, carbolic acid, or cresol, or mixtures of these, the solvent being used in a proportion of 1 or 1,5 of solvent to 1 part of coal.  The extracts are ground, mixed with a binding agent, and pressed into the desired shapes before subjecting to heating.  They may be subsequently graphited by being heated electrically by induction currents, or by direct passage of a current, in a non-oxidizing atmosphere.  Specifications 234,564 and 268,372, [both in Class 91], also are referred to.
